Specification forhing part of Letters Patent No. l 74.8 [4, dated 14, 1876; application filed November '29, 1875.

To all whom' t may camera:

Be it known that l, LEVERETT T.- HARPER, of Owatonna, in the connty of Steele and State ot' Minnesota, have invented certain new and useful Improvements in Submerged Pnmp, ot" which the following isa specification:

The nature ot' my invention consists in the construction and arrangement of a submerged i'orcepump, as will' be hereinafter more fully set forth.

in order to enable others skilled in the art to which ny invention appertains to make and use the same, I will now proceed to 'describe its Construction and operation, refexring to the annexed drawing, which forms a part of this specification, and in which- Figure l is a side elevation of my forcepump. Fig. 2 is a longitudinal section of the same. Fig. 3 is a detail, showing the screen as now applied, and the piston. Fig. 4 shows the packingrings used in the piston.

A represents the pump cylinder closed at its lower end and open at the top. On one side of the cylinder A, and extending nearly the entire length, is a chamber, B, which is entirely closed, except near the top, where a strainer, a, is inserted, as shown in Fig. 2. The pnmp is to rest on the bottom of the well, and the water passes through the'strainer a into the chamber B. Within this chamber,

-near the lower end ot' the cylinder, is a collar,

I), projecting from the cylinder and surrounding an aperture the ein. In this collar ortnbular projection is hinged a valve, G, which opens inward and npward to admit the water from the chamber B into the cylinder. posite side of the cylinder, at or near the bottom,projects an telbow, D, the top of which forms a horizontal valve-seat for the checkvalve E, said Valve opening upward. At the upper end of the elbow D, above the valve, is formed a socket for the insertion of the pnmpstock or ontlet-pipe H, which is closed at its upper end, and on one side provided with a spout, I. By admitting water into the side ot' the cylinder it can sit frmly on the bottom of the well, thus allowing the piston or plunger to be as nearly submerged as the water in the well will allow. T-he valve O being hung at the top prevents it getting clogged or in any way On the op-' getting out of order. The elbow D forms a chamber below' the .valve E, which, together with the level valx e-seahprevents anything from lodging'under the valve which -would' packing-rings d d', which are expanded bythe water passing through passages e e into the grooves behind the packing-rings. On the upstroke of the piston the water expands the upper ring d, and on the downstroke it is the lower ring d' which is expanded. The advantages of having a suction-packing as well as at'orce-packing are that, oftentimes, the Water in the wells where this pump is used gets very low. In this event the suction-packing performs a very valuable function in` filling the pump. The body J of the piston may be made of one or morepieces, as desired, and is connected by a pivoted rod, K, with the handle L, which is pivoted tothe pumpstock H. The connection between the handle L and rod K is made by a pivot-bolt, h, as shown, which allows ot' the handle falling down When the pump is notin use. The upper end of the pumpstock H is provided with a cap, P, having a rim, t', to drive into the stock, and in thecenter of the cap is a screw, R, to give the pump vent or make it air and water tight, as may be desired. The handle L is connected to the punpstock by cnrved rons M, as shown, whereby the handle may be arranged so as to govern the length of the strok'e, and drop down when not in use. rings are joined together, as shown in Fig. 4, the joint being made in the form of a Z, so as to make a continuous joint either way. The cylinder may be made either wholly or in part of metal or wood, as may be deemed most desirable and the strainer in the chamber B may be inserted at such point as is necessary or desirable, in order to admit the water according to the depth of the water in the well.

Having thns fully described my invention, what I claim as new, and desire to secure by Letters Pat-ent, is

1. The combination of the cylinder A, chamber B with strainer a, and the valve C open.-

The packinging inward and Upward into the cylinder, suhstantially as and for the purposes herei set v fOI'th.

5. In combinaton with pump-cylinder A, having ilet-valve C, as described, and provided with pisten J, the elbow D, connecting at the bottom with the lower end of the pumpcylinder, and having at its upper end a level valve-seat for check-valve E, and supporting the pumpstock H, all substantially as and for the purposes set forth. 4

In testimony that I claim the foregoing as my own, I affix my signature in presence of two witnesses.
